Why Choose Raytron?
Founded in 2012, 15,000 tons/year capacity, 13 precision rolling lines
RAYTRON New Energy (Zhejiang) Co., Ltd.: Raytron manufactures composite PV ribbon and precision clad conductors, including CCA, CCS and NCC materials for solar, cable, EV, motor and energy applications.
Our Clad & Weld solid-phase bonding process forms a metallurgical interface at the Cu-Al boundary. Bond integrity is verified per the product control plan through metallographic examination, peel or shear testing and resistance checks. Combined with precision rolling, annealing, slitting and surface treatment, we support PV, new energy, electrical connection, cable and high-end conductor applications.
Core Technical Advantages
- Conductivity: CCA products specify 62-70% IACS depending on copper cross-sectional area ratio and product form
- Lightweight: 58-63% weight reduction at equal dimensions compared to pure copper; system-level weight reduction depends on conductivity, conductor size, insulation, termination and application design
- Cost Indication: Indicative material cost comparison depends on copper ratio, dimensions, volume and copper price; quotation is provided after specification review
- Customization: Round wire, flat wire, strip, foil and stranded forms can be reviewed against application requirements
Our products are used in photovoltaic solar, electric vehicles, energy storage systems, communication cables and high-end conductor applications. Supplier qualification status is confirmed per customer audit and application validation.
